1. The problem statement, all variables and given/known data Grounded conducting sphere in uniform electric field has potential V(r,θ) = -Vo(1 - (R/r)3)*cosθ Find Er and Eθ. 2. Relevant equations 3. The attempt at a solution In the text book I found Er = -∂V/∂r Eθ = -1/r ∂V/∂θ Those are in the chapter we're working with but those two equations are in the section talking about the electric field of dipoles. Do those equations apply for the problem I'm working on?
